Stettktlldi Specification of Lettersv Patent.-

Application filed July 8. 1909. Serial No. 506.5%.

lb all a-hom ii into/"concern:

Be it known that l. llxunv (Ant liuuau, a

citizen of the l nited Fwtates. and a resident ot Monongah, in thecounty of Marion and State of Vest 'irginia, have invented a new andImproved Gas-Burner, of which the fol-- lowing a full, clear, and exactdescription.

Among the principal objects which the present invention has in view are:to proturning the tube 8 it is advanced or receded bv the screw threadsshown at S) to advance or re ede the bevel end H3, and thus contractvide 'an apparatus wherein air steam and gas are mixed and burned; toprovide an apparatus whercln the quantity of gas being mixed with theother ingredientsmay he i regulated; and to provide an apparatu.--:

; sition by a suitable nut 18, which engages the external threads formedon the end of wherein the construction is at once simple, durable,economical, and ellicient.

()ne en'ibodiment ot the present invention disclosed in the structureillustratml in I the accon'ipanying drawings, in which like charactersof reference denote corresponding-parts in both views, and in which--Figure 1 is a perspective view of an apparatus constructed in eontm'mitywith the present invention; and Fig. 2 is a vertical longitudinalsection of the same.

The apparatus hereinshown and described is generally used in a furnace,the burner feed pipe 3 whereof is engaged by a bcllshaped end 4 of atube 5 constituting the body of this apparatus. The tube .3 is providedwith a lateral extension (3, which screw threadably COllllOtiiCCl with agas supply pipe 7. The end of the straight section of the tube 5opposite the bell-shaped end i, provided with screw threads internal andexternal. The internal threads are provided to receive correspondingthreads formed on the body oi. a tube 8, as seen at i). The tube 8 is ofa straight body provided with a llaged end section it), the. section 10being driven onto the said tube 8. i The end section It) is provided tosupport a spider 11, whichcarries a perforated and screw threaded hubt2. Extended through the perforation in the hub 1.2, and held therein bythe screw threads shown at 13, is a small pipe 14; suitably connectedwith a steam supply pipe, not shown in the present drawings. The pipe'l-iis extended within the tube 8 to near the end thercot and isprovided with a contracted nozzle '15 provided to produce a rush of thesteam as delivered tron'i the pipe 14'.

The tube 8, supporting the pipe 1+, normally extends within the straightsection of the tube 5, past the cxtrance oi the exten sion (.3, into thetube .3. The inner end ol the or expand the opening for the passage ofthe gas from the extension (3 to within the tube or mixing chan'iber 5.

lhe joint between the tubes 5 and 8 is sealed by packing 17, which isheld in pothe tube The operation ot" an The "as having been turned onthrough the pipe t and extension (3, it blows into the tube 5 andbell-shaped end si and teed pipe 3. The steam is turned on at it, Therush of the steam from the contracted end of the pipe It produces asuction within the tube 8, causing the air to flow in through theopenings 19, 19 in the end section 10, and thence through the tube 8 tothe feed pipe When the gas is being ignited it may prove advantageous tohave the same as rich in gas as possible, in which case the steam is notadmitted through the pipe 14, and the air may he excluded from the tube8 by blocking the openings 19, 19. When, how.- ever, the ignition hasoccurred, the openlugs 19, 1.) are exposed, permitting the air to tlowinto and mix with the gas in the pipe 3, passing thence to the burner acomluistiblc material. The steam is then admitted through the pipe 14,producing the el'lect mentioned of accelerating the flow of air throughthe tube 8. A further citcct is produced by the admission of steam, inthat the steam is mixed with the air and gas, add.- ing materiallyto-the combustible and heat producing quality of the gas as it entersthe combustion chambers thoroughly mixed and highly heated.

I have provided in the side of the tube 5, between. the extension 6 andbell-shaped end 4, a series of perforations 20, 20, Which are employedto augment the supply of air to the pipe 3.

Having thus described my invention, what I claim as new and tore Patentis desire to secure by Let" apparatus con-, rdiltt'lctl as abovedescribed is as tollows:

with a gas pipe, an air 1. A gas burner, consistin of a tubular bodyhaving one end bell-shaped and its other end internally and externallyscrew threaded, the body bein provided with a plurality of openlngs ajacent to its bellshaped end and with a lateral extension intermediateof its ends for connecting a as pipe thereto, an air tube having abeveled inner end and a flared outer end provided with a spider having acentral and internally threaded hub, the said tube being externallyscrew threaded and screwing into the body with its inner end projectingover the lateral extension thereof, a steam pipe screwing into the hubof the spider of the air pipe and havs ing a nozzle at its inner end,the steam pipe extending into the air pipe to within a short distance ofits inner end, and a nut on the air pipe and screwing onto the body.

2. A gas burner, comprising a tubular body havin one end internallyscrew threaded an provided with openings adjacent to its other end andintermediate of'its ends with a lateral extension for connection pipehaving a beveled inner end and a flared outer end', the air pipe beingexternally screw threaded and screwing into the body with its inner endprojectin over the lateral extension thereof and the flared end of saidpipe being provided with a central and internally threaded hub, and asteam pipe externally threaded and screwing into the hub of the airpipe.

3. A gas burner, comprising a tubular body internally screw threaded atone end and provided intermediate of its ends with. a lateral extensionfor connection with a gas supply, an air pipe of slightly less diameterthan the body and having a beveled inner end and a flared outer end,said pipe being externally screw threaded intermediate of its ends andscrewing into the body with its beveled inner end extending a shortdistance beyond the lateral extension of said body and controlling theflow of gas through the same, the flared end of the said pipe beingprovided with a spider having a central hub, and a steam pipe secured inthe hub of the spider and extending into the air pipe to within a shortdistance of its inner end.

4. A gas body having a lateral extension intermediate of'its ends forconnection with a gas supply, an air pipe of slightly less diameter thanthe body and adjustably mounted in said body with its inner endextending a short distance beyond the lateral extension and serving to 1control the flow of gas through said extension, the outer end of the airpipe being flared and open, and a steam pipe supported in the flared endof the air pipe and extend 1 ing to within a short distance of its innerend.

v In testimony whereof I have signed my name to this specification inthe presence ot two subscribing witnesses.
